What it does and how it helps Function: transfers or reduces screw size to connect components with different thread or head dimensions. Compatibility: works wherever a screw size adapter is required — follow the specification Size = M1 * L1 - M2 * L2 to match your screws. Performance: durable material minimizes wear from repeated installation and removal, keeping fit and alignment reliable. Practical features Simple installation: replace or insert to adapt screw dimensions without special tools in most cases. Reusable design: can be used repeatedly for maintenance, prototyping, or retrofit tasks. Precise fit: designed to provide a tight connection between mismatched screw sizes when matched by the specified dimensions. Use scenarios Furniture repair: adapt a replacement screw to fit existing threaded inserts or brackets without replacing the insert. Electronics or appliance servicing: fit replacement fasteners where original parts are no longer available or have different head sizes. Prototyping and small machinery: quickly test assemblies with differing screw sizes during design or maintenance. Notes for selection Confirm the required sizes using the format Size = M1 * L1 - M2 * L2 before ordering to ensure compatibility.
